I ran into the same issues that you did… self managing is great, but you need help in order to scale and grow your businessSo now I’ve got people offshore managing my properties at a very high quality for a fraction of the cost, something worth considering.Mine can set door codes, message (or call) guests, schedule cleaners, adjust the thermostat, monitor my cameras, & call a plumber just as easily as a local PM can, for 1% of the costThey handle everything themselves and rarely need to get me involved in anything, it is the perfect hands off low cost operationI wrote much more about leveraging offshore assistants in this post here.

Back in the 80s, I was accepted into a graduate programme at MIT on "tuition remission" - I pay for the first year and, pending my performance, MIT would cover the second year.  

With wifi locks, wifi thermostat, wifi cameras and your team, you can easily do it.  

They love the view of the lake from our screened back porch that has rocking chairs.They love the water and the water toys we provide.I love my Honeywell wifi color touchscreen thermostats. 9000 series.I live my wifi Rheem water heaterI love my digital watchdog hardwired security cameras.

Being a programmer, I didn't really want to spend all the time navigating my county's tax assessor's site for dozens of addresses at a time, so I made a script to do it for me.Anyhow, the short of it comes down to a pretty simple question: What am I looking for?

I dont get many Airbnb bookings so that is less of a concern for me.I have a lockbox that has never failed, never needed batteries so I haven't been motivated to fix what isn't broke.I do have wifi thermostats and hot water heater as well as hard wired security cameras (no batteries to replace)

Two - install a basic HVAC system that can be controlled by a thermostat. 

We have ring doorbells/floodlights, august smart locks, noise aware for outside noise monitoring, and nest thermostats in all of our units.Also, if you can, speak to the neighbors and introduce yourself.

Today she informed me that her son in law changed the thermostat in my unit and claims the neighbor next door has control of her furnace(not possible).

It takes work to maintain that script, though, it's not something a non-programmer could maintain; plus, I have to already have interpreted the meaning of each document, and named the files in a unique way that includes the date, so that the Perl script files it away in the right place.If I could automate the web-site interactivity part, and connect that to a calendar-based trigger of some sort (on the last day of the month, login to THESE sites and download all the files), that would go a long way to freeing up my time.As a real estate investor, I want the freedom to have 10X the properties I have today.
